March made bearable by fragrant clusters of clean-white flowers on this bright-green, leather-leaved evergreen
- Position: full sun
- Soil: fertile, well drained
- Rate of growth: fast-growing
- Flowering period: early spring
- Hardiness: Frost hardy (needs winter protection in cold areas)
- Pruning: Group 1
A fantastic, evergreen, twining climber, with handsome, long, lance-shaped leaves that will cloak a wall or fence within a few seasons. In early spring, it’s smothered in fragrant, four-petalled, star-shaped white flowers and the new leaves are bronze-tinted. Plant near a doorway to enjoy the scent, and give it plenty of room to spread out.
- Garden care: Clematis armandii prefers its roots to be in cool, moist, well-drained soil, so plant deeply in a shady spot and water well. Mulch around the roots each spring with well-rotted garden compost or manure. This clematis does not like cold winds, so choose a sheltered spot in the garden.
This plant is toxic to dogs if eaten.

Q:What is the best time of year to plant this clematis? We've just cleared our overgrown garden and are planning on growing this over an ugly garage.Asked on 29/11/2016 by Apollo69 from Surrey
As a general rule fully hardy plants that are grown in containers can be planted at any time of year as long as the soil isn't frozen solid. The best times are in the autumn when the soil is still warm enough to encourage root growth but the plant isn't in active growth, or the spring before the temperatures start to rise.
However this clematis is not fully hardy, it is only frost hardy so unless you are planting it in a very sheltered spot, and the ground isn't frozen or freezing outside I would wait until the spring now.Answered on 30/11/2016 by Anonymous from crocus
Q:Hi, we're looking to buy a climber to cover a corner of our two-story home. We currently have honeysuckles, but they are not evergreen and their foliage is very bare. Would this be a good evergreen alternative? Our corner is East/North East facing. Also, I wanted to know the difference between Clematis Armandii and Clematis Armandii Snowdrift? Thank you!Asked on 9/8/2015 by Hizzy from Lancashire
These plants will tolerate partial shade, however they will flower best in a sunnier spot, so while they will offer year-round foliage (if the spot is reasonably sheltered and not too dark), they wont put on a dazzling display in spring.
As for the difference between these two Clematis, the main one is the flowers. The petals of 'Snowdrift' are slender, so give the flowers a lighter, almost star-like appearance.Answered on 12/8/2015 by Helen from crocus
Q:I have a clematis armandii trained a cross south facing fence. However despite producing abundant green growth and leaves, it has never flowered in the four years it has been there. The growths that look like possible buds never open. any advice please? Green fingers surrey.Asked on 23/3/2014 by Greenfingers1 from South west surrey
There are a number of reasons why plants don't flower including too much shade, not enough water or nutrients, or pruning at the wrong time of the year. It can also be caused by the plant putting on new root growth instead of focusing its energies on producing flowers. I am not really sure why yours has not flowered, but it sounds as though it is healthy enough so you can often give it a bit of a push by feeding with a high potash fertiliser. I hope this helpsAnswered on 25/3/2014 by Anonymous from Crocus
Q:Is clematis armandii a suitable climber for a north facing 6' fence, or would it be too vigorous height-wise? There is plenty of room horizontally.Asked on 4/2/2013 by madmaia from Anglesey (coast)
These plants have an eventual height of 5m and spread of 3m, so unless you are prepared to keep tying it in to the fence, it will quite quickly outgrow its allotted space. A bigger concern however would be the northerly aspect as it will prefer a little more sun.
I hope this helps,Answered on 5/2/2013 by Helen from Crocus
Q:Cutting back an evergreen Clematis armandii
I have a four year old Clematis that I had to cut back to within 3 feet of the ground a couple of weeks ago due to an unsafe structure nearby. The stem is slightly thicker than the diameter of a 20p coin. It has started to ooze lots of sap which is continuously running down the trellis. Should I have sealed it with something? Do you think it is likely to survive? ThanksAsked on 13/4/2010 by Gill Green
A:Hello There, These Clematis dislike being cut back hard and it sounds as if it may not survive. The stuff oozing out is the sap, which is rising fast at this time of the year. I doubt you could have sealed the wound to prevent it. Unfortunately this is not a great scenario though as this is effectively the plants lifeblood, but I would leave it for a few months and see if it settles down and start to put on new growth. Don't feed it with anything and just make sure it gets adequate water - and keep your fingers crossed. I'm sorry not to be more help. Helen Plant DoctorAnswered on 13/4/2010 by Crocus Helpdesk
Q:Advice on climbers please
Hi, I need to find climbing plants for the length of a 2m high wood panel fence with concrete posts. I haven't measured the entire length but I would estimate around 15m. It is South facing and on a side of the garden that gets a lot of sun in the summer, the soil is clay and tends to dry out. I have no idea how many plants I would need to cover the entire fence (I am notoriously bad at judging the spread of a plant and always end up with an overcrowding problem). I am looking for something to deter anyone from climbing over the fence, yet ideally something that won't be treacherous to deal with myself (if such a plant exists!). Climbing roses are the first to spring to mind and if I were to go down that route I would definitely opt for white or cream flowers. I have had a look at the white climbing roses on your site but am unsure whether they will be happy in our soil, as you specify 'moist, well-drained' humus rich soil. I would also like to get an evergreen climber for the rear fence (+/- 5m long). I am not concerned whether this flowers or not, and I am less concerned about this being a 'thief-deterrent'. The soil is the same,- lots of clay, which plants seem to like, but it is very hard to work with and dries out easily in the summer. Any advice gratefully accepted! Best regards, HeatherAsked on 12/3/2010 by Thuli
A:Hello Heather, Unfortunately there are no plants that will deter intruders without being difficult to deal with, and the best plants are those with thorns like the roses. It sounds like roses will certainly grow in your soil, but ideally you should dig in lots of composted organic matter and then make sure they are kept well watered in summer. It can be difficult to see a small plant and imagine how big it will grow to eventually, however we do give all this information on each plant card, which hopefully should help. You will find it just to the right of the pictures at the top of the pages. If you click on the following rose, you will see it has an eventual height and spread of 10 x 6 m http://www.crocus.co.uk/plants/_/roses/climber-rose/rambling-roses/climbers/rosa-filipes-kiftsgate/classid.1280/ while this one will only grow to 3 x 2m http://www.crocus.co.uk/plants/_/roses/climber-rose/climbers/climbing-roses/rosa-climbing-iceberg/classid.1181/ I would pick the one you like the look of and then you will be able to establish how many you need to fill your fence. As for the evergreens, if you click on the following link it will take you to our full range of evergreen or semi-evergreen climbers that will grow in clay soils, but the same rules apply re preparing the soil and watering. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.9/vid.228/ I hope this helps.

Q:Climber for South facing wall
Dear Sir/ Madam, I wanted to order a couple of climbers for a south facing wall. I already have a Virginia Creeper growing but the wall is concrete and looks terrible in the in winter. Have you got any recommendations for an evergreen climber that would grow well on a south facing wall, and also grow with a Virginia Creeper? Kind regards, RolandAsked on 10/12/2009 by s8films
A:Hello Roland, The best will be the Hederas, which are self-clinging like the Parthenocissus - just click on the link below to go straight to them. http://www.crocus.co.uk/search/_/search.hedera/ If however you can put up a network of wires or trellis, then you can choose from any of the following. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.228/ I hope this helps.

Q:Climbers to cover a Pergola
Hello We are building a 13ft square x 8ft high pergola and want to have Clematis, with flower for most of the year, but also with vigorous growth to cover the roof of the pergola. What Clematis would you recommend or do I need to include climbers like Jasmine and Virginia Creeper to provide summer and autumn colour? Please advise PaulAsked on 3/11/2009 by Anonymous
A:Hello Paul, I'm afraid no single Clematis will flower throughout the year, however you can get different types to flower at different times of the year. As a very general rule the group 1 Clematis are early flowering, the group 2's mid and the group 3's late, so this will help you narrow down your selection. The following link will take you to the few evergreen Clematis, some of which are quite vigorous - you can see the eventual height and spread of each to the right of the photos once you open up each page. http://www.crocus.co.uk/plants/_/climbers/clematis/plcid.15/plcid.16/vid.24/ I hope this helps.

Q:Looking for a suitable plant to screen pipe
I am looking for advice please. We have recently installed a downstairs toilet which involved erecting a very large ugly grey pipe (vertically) which almost reaches the eaves of the house. The position of the house/pipe wouldn't be suitable for a tree as it is directly on the driveway side of the house. Could you possibly suggest a fast growing bushy evergreen climber to disguise it? I'd thought of ivy but perhaps you could suggest something bushier or better?Many t hanks ElizabethAsked on 17/10/2009 by elizabeth cairns
A:Hello Elizabeth, There are very few truly evergreen climbers that are fast growing, so ivy may be a good option. Another option may be Clematis armandii, but this is not quite fully hardy - just click on the following link to go straight to it
or if you want a semi-evergreen, then these two might be worth considering. Lonicera japonica Halliana
or Solanum (again not quite fully hardy)
